update_webhook

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate the tool is idempotent and non-destructive. The description adds no additional behavioral context beyond 'Update', which is consistent. No contradictions, but the description fails to disclose any extra traits like authentication requirements or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, short, front-loaded sentence that efficiently conveys the tool's function with no extraneous words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple update tool with 4 parameters, the description covers the key aspects that can be updated. While it could mention whether updates are partial or full replacement, the annotations and schema provide additional context. The description is mostly complete for typical usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaning by linking the updatable fields (endpoint URL, events, status) to the parameters endpoint, events, and status. With only 25% schema description coverage, this compensates partially. However, the required 'id' parameter is not mentioned in the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Update' and the resource 'webhook', and lists specific updatable aspects (endpoint URL, subscribed events, enabled status). This distinguishes it from sibling tools like create_webhook, delete_webhook, and get_webhook, making the purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for updating an existing webhook, but does not explicitly state when to use it vs alternatives (e.g., create_webhook for new webhooks) or provide any exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
